APPARATUS FOR MAKING REINFORCED FENCE-POSTSDF ELASTIC MATERIAL.

Specification of Letters Patent.

Application filed July 11, 1910. Serial No. 571,434.

To all whom it may concern.

WELL, citizen of the United States, residing at Manhattan, in the countyof Riley and State of Kansas, have invented new and useful Improvementsin Apparatus for Making Reinforced Fence-Posts of Plastic Material, ofwhich the following is a specification.

My invention pertains to apparatus for making reinforced fence posts ofplastic material; and its novelty, utility and practical advantages willbe fully understood from the following description and claim when thesame are read in connection with the drawings, accompanying and formingpart of this specification, in which:

Figure 1 is a plan illustrating the manner of making two fence posts inmy novel apparatus at one time. Fig. .2 is a vertical longitudinalsection, taken in the plane indicated by the line 2-2 of Fig. 1, andshowing the fence post partly broken away. Fig. 3 is an elevation of oneend of the apparatus.

Fig. 4 is a transverse section taken in the;

plane indicated by the line H of Fig. 1, looking in the directionindicated by arrow. Fig. 5 is a section taken through one of the postsand illustrating one of the crosswise reinforcements and wire holderstherein. Fig. 6 is a detail perspective view illustrative of the mannerin which the bights of the main reinforcing loops in each post arebrought together at the upper end of the post. Fig. 7 is a detailsection illustrative of the said feature.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A is the base of my novel apparatus.

B is a longitudinal wall seated in a longitudinal groove a in the upperside of the base, and B, B, are longitudinal walls arranged at oppositesides of and spacedfrom the wall B and seated in longitudinal grooves ain the upper side of the base. The

D D are corner bars, four in number, nailed orotherwise fixed to thebase A, and E E areremovable corner strips, fourin number. Each of the end walls 0 and G is provided with a pair ofapertures c and a pair of apertures (Z; the apertures cl being disposedat one side of and lower thanthe apertures 0. It will also be noted that.each end wall is provided at a point below its pair of aperturescl'with a recess 6; the said recess being in the inner side of the wallas clearly appears in Fig. 2.

In the practical use of my novel apparatus the end walls C C arearranged at the inner sides of the cleats 5, and the strips E arearranged in the manner shownthat is to say, one pair of strips E ispassed through the higher apertures 0 of the end wall C and into thelower apertures d of the end wall C, and the other pair of strips E ispassed through the higher apertures c of the end wall C and into thelower apertures d of the end wall C The concrete or other plasticmaterial of which the posts are to be formed is then tamped in theapparatus up to a point flush with or adjacent the upper sides of theinclined strips E; the metallic reinforcements F and G being placed inposition at the proper time and so that the bights f of thereinforcements F rest in the before-mentioned recesses e in the innersides of the end walls G and C After the placing and tamping of theconcrete is completed, the formed posts are allowed to set, and when thesame have hardened sufficiently, the end walls C C and the strips E areremoved, whereupon the posts may be expeditiously and easily lifted frombetween the side walls B and B By reason of the end walls C C beingreduced in height at one end and reversely arranged, and the walls Bbeing reduced in height from one end to the other and reverselyarranged, it will be manifest that the tapered posts may be veryconveniently PatentedMay-V, 1912.

manner described, two posts can be prothere are two in each plasticpost, are in the form of open frames or loops of heavy wire, and thesaid loops are arranged side by side for the greater port-ion of theirlength, while their bights f are brought together and disposed in therecesses e which serve to hold the bights f in said relation until theconcrete or other plastic material sets or hardens when it will serve tohold the bights f together notwithstanding the tendency of the same tospring apart because of the resiliency of the loops. The reinforcementsG of Wire are also placed in position at the proper time incidental tothe formation of the plastic posts, and said reinforcements G areprovided at their ends with loops 9 which are made to extend beyond oneor two sides of each post.

WVhen-the posts are completed and set up ready for use, the bights f mayobviously be used for the connection of acrown fence wire, while theloops 9 of the reinforcements G may be used for the connection of runnerwires at points intermediate the ground and the upper ends of the posts.

While I have shown and described one form of my invention, it is to beunderstood that I am not limited to the details or the form or relativearrangement of parts disclosed, but that modifications may be madetherein without departing from the spirit thereof.

Having described my invention, what I claim and desire to secure byLetters-Patent, is:

An apparatus for use in the production of posts of plastic material,comprising a base, three side walls arranged on the base; theintermediate side wall being of even height throughout its length, andthe outer side walls being tapered in height from one end to the otherand being reversely arranged, end walls reversely arranged on the baseand removable therefrom and each having a high portion and a low portionand each also having a pair of apertures in its high portion and a pairof lower apertures in its low portion; the lower apertures of each endwall being arranged opposite the upper apertures of the other end wall,and four longitudinal strips removably arranged in the apertures of theend walls and so that each strip is disposed in one of the higherapertures of one end wall and in one of the lower apertures of theopposite end wall; each strip being also arranged directly against theadjacent side wall.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
